Figure 6. Root BR, GAs, IAA, and MeJA concentration of trifoliate orange (P. trifoliata) seedlings colonized by D. versiformis under well-watered and drought stress conditions.

Data (means ± SD, n = 4) followed by different letters above the bars indicate significant differences (P < 0.05) between treatments. Abbreviations: same as for Fig. 1 and BR: brassinosteroid, GAs: gibberellins, IAA: indole-3-acetic acid, MeJA: methyl jasmonate.
